Olivia confesses she has been thinking of nothing but her child recently.

The prospect of becoming a mother in a month’s time has left her unable to focus on much of anything else.

“Baby brain is real. I should not be permitted to operate heavy equipment including iPhones,” she joked.

Apparently Olivia’s future husband, We’re the Millers star Jason, was a hardcore partier in the past.

But it is claimed their romance has transformed his bad habits for good.

“Olivia is obsessively anti-drug, and Jason has had to leave behind a lot of his old party pals and drinking buddies since he’s been with her. This is a pretty sensitive issue for her,” an insider informed Radar Online previously.

“Olivia and Jason live an extremely clean life and try to get away from their respective past demons in the process. They’re going to make great parents.”

Jason and Olivia became engaged in 2013 after 14 months of dating. Copyright: Cover Media 2014
